      abstract     = {The mobility of copper ions and redox reactions of Cu at
                      the interface with SiO(2) being directly attributed to the
                      resistive switching effect have been studied by cyclic
                      voltammetry (CV). The electrode kinetics of the Cu(z+)/Cu
                      redox reactions were analyzed suggesting the formation of
                      both Cu(+) and Cu(2+) species. The ion mobility shows an
                      unexpected strong dependence on the ion concentration
                      indicating ion-ion interactions typical for concentrated
                      solution conditions. Based on the standard reduction
                      potentials for Cu(z+)/Cu we identified partial
                      electrochemical redox reactions during oxidation and
                      reduction. The results contribute to a detailed
                      understanding of the resistive switching effect in
                      Cu/SiO(2)/Pt cells and provide insight into
                      electrochemically assisted diffusion of metal cations in
                      oxides in general.},
